California Fitness CF 4007 Hyper Extension

California Fitness CF 4007 Hyper Extension

The California Fitness CF 4007 Hyper Extension is a dedicated strength-training machine designed for hyperextension and back-extension exercises, helping users target the lower back, glutes and hamstrings in a controlled training position.

Its angled design features padded upper-body supports, adjustable positioning, leg and foot support, and a wide stabilizing base, creating a secure setup for performing back-extension movements. The supported position allows users to focus on controlled movement through the hips and lower back while maintaining a stable lower-body position.

Designed with a gym-style frame and practical adjustment points, the CF 4007 is suitable for both dedicated strength-training areas and facilities where focused posterior-chain training is required.

Targeted Muscle Groups

The CF 4007 is primarily designed to train the posterior chain, making it useful for strengthening several important muscle groups.

Primary Muscles

• Erector Spinae / Lower Back

• Glutes

• Hamstrings

Supporting Muscles

• Hip and lower-back stabilizing muscles

• Core musculature

The exact muscle emphasis can vary depending on exercise technique, body positioning and range of motion.

Controlled Hyperextension Training

The CF 4007 provides a supported setup for performing hyperextensions and back extensions. The padded support helps position the upper body while the lower-body supports help keep the legs secure.

This allows users to concentrate on controlled hip and trunk movement rather than having to stabilize themselves on a basic bench or improvised setup.

Comfortable Support During Workouts

The machine incorporates padded contact surfaces at the main body-support areas. These supports are designed to provide a more comfortable training experience while maintaining the user's position during repetitions.

The dedicated foot and lower-leg support further helps create a secure training position, particularly during controlled movements.

Stable & Practical Design

A stable base is important when performing exercises involving repeated forward and backward movement. The CF 4007 features a broad, structured frame designed to provide a firm training platform.

Its straightforward design also makes it easy to incorporate into a dedicated strength-training area alongside benches, free weights and other lower-body equipment.
